Patented Nov. 8, 1938 UNITED STATES PATENT OFFIQE 2 Claims.

This invention relates to a combination structural assemblagecharacterized on the one hand by an improved bottle neck construction;and having reference on the other hand, to an espe- 5 cially designedhood-type closing cap therefor.

Visualizing with greater particularity the bottle neck structure alludedto in the introductory statement, it will be observed that one object ofthe invention is to provide an improved milk 10 bottle having a smoothinternal pouring surface provided in the neck thereof, and havingexternal .features embodying a ledge forming bead cooperating with arelatively smaller annular rib constituting a cap adapter and retentionlip.

15 A further feature of the invention is the composition hood-capcharacterized by a disk-like body portion and an annular attaching rimwherein said rim is provided with an annular flange terminating in abinding or clamping flap 20 susceptible of being clenched between therim and flange, said flange being constructed to provide anaccommodation channel for a stabilizing and retaining ring. 1

Other features and advantages may become 25 more readily apparent fromthe following description and drawing.

In the drawing, wherein like numerals are employed -to designate likeparts throughout the views:

30 Figure 1 is a sectional view showing the bottle neck construction andassociated especially designated cap fitted thereover in bottle-closingposition.

Figure 2 is a bottom plan view of the cap per se.

35 Figure 3 is a section on the line 3--3 of Figure 2.

Figure 4 is an exaggerated or magnified view showing a fragmentaryportion of the laminated construction. I

Figure 5 is a detail view of the radially expansible' and contractablesplit metal retaining ring.

As shown in Figure 1 the milk bottle is denoted by the numeral 5 and ischaracterized by a smooth liquid-pouring neck I having outstanding capThe main outstanding annular bead 8 is spaced down from the mouth of theneck and in effect provides a ledge for the hood-type cap 9. Disposedaround the mouth and spaced from the shoulder or ledge 8 is a rela- 50tively small endless or annular bead l forming a lip and in eflectdefining a channel between itself and the ledge 8. In other \"ords,these spaced apart beads 8 and I0 provide the desired retention means,channel, ledge and lip.

5 The hood-cap is of the so-called waxed cardboard or paper group and isof the laminated construction shown in Figure 41 That is to say,

it includes a flexible body portion II and inner and outer coatings orfilm of wax or paraffin as indicated at l2. The cap is characterized bya 5 disk-like lid or cover portion and a depending skirt or rim I3, thelatter feature being properly expansible and contractible and of annularform so as to fit down over the lip l0 so that it can rest on the beador ledge 8. The seating portion of 10 the rim is formed into an inturnedfold or bend as indicated at It and beyond the bend it is fashioned intoan annular binding and clamping flange 15. The flange terminates in adown-bent clinching flap lfiwhich when in clamped position '15 as shownin Figure 1 is located between the rim l3 and the flange l5. The bend I4cooperating with the features l3 and defines a channel to accommodatethe resilient split retaining ring IT. This is of such a diameter as topermit it to snap into the channel formed between the heads 8 and I0.

It is evident that by slipping the multiple featured rim of thehood-like cap 9 down over the neck'of the bottle, the mouth of thebottle is covered by the disk portion while the rim is clinched into thechannel formed between the lip Ill and ledge 8. The triple thickness ofmaterial provided by the features l3, l5 and i6 permits a firm clampingaction to be obtained and provides a rolled edge at the point l4, all ofwhich features in conjunction with the ring I! offer their contributoryor proportionate share in affording an effective binding and clampingaction. It follows, therefore, that I have evolved and produced a simpleand economical aptly fitted bottle neck and cap construction. A cap ofthis type is easily applied at the time of charging the bottle with milkat the dairy.. It is readily retained in place during transit andthereafter easily removed and replaced by the housewife. Obviously,therefore, I haVeperfected an ingenious assembly which, it is believed,adequately fulfills the requirements of a structure of thisclassification. I

the field of invention claimed may be resorted to if desired.

What is claimed is:-

I. In a structural assemblage of the class described, a milk bottleincluding a neck having a smooth internal surfaced portion defining thepouring mouth, said neck being externally formed with an inwardlylocated, radially outstanding bead constituting a ledge, and beingfurther provided at its outer end with a second outstanding bead, saidsecond-named bead being of a diameter less than the ledge andcooperating with the ledge in defining a keeper channel, a hood capincluding a disk-like portion and an annular rim portion, said rimportion being of multiple ply thickness and fashioned for reception insaid keeper channel, and being possessed of porous absorbent propertieswhereby when it is moistened it swells and lodges itself .firmly in aclamping position in said keeper channel, and a metal ring located insaid rim and of a diameter correbent flange terminating below thedisk-like closure portion, and said flange terminating in a return bendforming a lip, the rim and said flange constituting a channel and saidlip depending into said channel, and a metal ring located in the channelin the manner and for the purposes described.
